Cerebral venous sinus thrombosis (CVST), cerebral venous and sinus thrombosis or cerebral venous thrombosis (CVT), is the presence of a blood clot in the dural venous sinuses (which drain blood from the brain), the cerebral veins, or both.
The superior sagittal sinus (also known as the superior longitudinal sinus), within the human head, is an unpaired dural venous sinus lying along the attached margin of the falx cerebri. It allows blood to drain from the lateral aspects of the anterior cerebral hemispheres to the confluence of sinuses .
The walls of the dural venous sinuses are composed of dura mater lined with endothelium, a specialized layer of flattened cells found in blood and lymph vessels.They differ from other blood vessels in that they lack a full set of vessel layers (e.g. tunica media) characteristic of arteries and veins.
The following is a partial list of the "C" codes for Medical Subject Headings (MeSH), as defined by the United States National Library of Medicine (NLM).. This list continues the information at List of MeSH codes (C13).
Non-traumatic causes of hemorrhage includes: hypertension, cerebral amyloid angiopathy, hemorrhagic conversion of ischemic infarction, cerebral aneurysms, dural arteriovenous fistulae, cerebral venous sinus thrombosis, cerebral vasculitis and mycotic aneurysm. [3] More than half of all cases of intracranial hemorrhage are the result of ...
This dural arteriovenous fistula of the superior sagittal sinus drains into subarachnoid veins and is classified as Borden type IIIb. Specialty: Neurology; Neurosurgery; Symptoms: Cognitive changes, including memory loss, rapidly progressive dementia, dyscalculia, hallucinations, psychomotoric slowing, apathy, disorientation, executive dysfunction
Non-developmental syndromes also directly or indirectly affect the Great Cerebral Vein of Galen, although they are extremely rare. These include superior vena cava syndrome (SVCS), and thrombosis of the lateral sinus, superior sagittal sinus, internal jugular vein, or of the Great Cerebral Vein of Galen itself. [citation needed]
The superior sagittal sinus divides into two parts called the transverse sinuses where the falx cerebri meets the tentorium cerebelli. [3] The sigmoid sinus, which continues the transverse sinus, empties into the jugular vein at the jugular foramen. The internal jugular vein leaves the skull and travels downward to the neck. [3]
